Sea water desalination
Chemical energy is released when the coal burns with oxygen in the air. This energy is used to heat water, which is converted into steam. Not all of the energy is used to heat the water. Some of it is wasted by being transferred as heat to the surroundings. The energy of the steam is used to turn the turbines, but some of the steam energy is wasted.
95%
The efficiency of a coal burning power plant is between 35% and 40%. This means that 40% of the energy is used to make electricity and the other 60% is wasted on heat and pollution through cooling towers and smoke stacks. This is the same efficiency that we had in the 1950s.
84% is wasted.
Electrical energy
Energy efficiency is the ratio between the useful power, and the electrical power used. If this ratio is - for example - 70%, that means that the remaining 30% of the input power is wasted.
It is wasted, and can no longer be used. Usually the energy will be in the form of heat energy, which is not concentrated enough to be of any use.
it is energy regeneration power plant in which water is used to generate power.water is moving on turbine and then turbine moves so energy stored in the resrvoir yhat is called as hydro power plant reservoir.
It is usually wasted.

Because the plant needs to use energy to live, and if the plant uses up the energy the herbivores can not receive it. There for some of the energy is used for the plant and what ever is left over is received by the herbivore.
